To use Google's reCaptcha feature, be sure to allow its public IP addresses.
To use the Box for Google Workspace, please go to the Google support pages for the hostnames you must allow. (You can ignore the Google Drive/drive IP addresses because this Box integration does not have a dependency on Google Drive.)

2. Enable HTTPS (port 443) for the domains above.
In case of Enterprise account, the customer may need add additional specific hostname in allowlist.
Please create a Box Product Support case and request the additional hostnames that are used with Enterprise accounts.
Due to the numerous firewalls available, we cannot provide specific instructions for each firewall beyond what is listed above. If you are using a firewall or proxy such as Forcepoint/Websense, Blue Coat, and so on, please create a Box Product Support case and request the additional hostnames that are used with Enterprise accounts.
Creating Allow Lists for Box Zones
If you have configured a firewall, you can allow the following Box Zones domains.
Canada
- fupload-ec2cac1.app.box.com
- fupload-ec2cac1.ent.box.com
- ec2cac1.boxcloud.com
Germany
- fupload-ec2euc1.app.box.com
- fupload-ec2euc1.ent.box.com
- ec2euc1.boxcloud.com
- ec2euw2.boxcloud.com
Japan
- fupload-ec2apne1.app.box.com
- fupload-ec2apne1.ent.box.com
- ec2apne1.boxcloud.com
Sydney, Australia

Box Desktop Applications' Proxy Support
Box Drive, Box Sync, Box Tools, Box for Office, and Box Notes Desktop are desktop applications that must connect to Box's data centers to function. The apps utilize the same domains outlined above. The apps detect and use the proxy configured for the local machine via:
- Automatic Proxy Detection
- Proxy Auto-Configuration (PAC file)
- Windows does not support local file path schemas for the .pac file location such as file://C:\proxy.pac. Use a URL to configure the .pac file location.
- Or manually setting the proxy server address for HTTP and HTTPS protocols
- Windows apps support NTLMv1 or NTLMv2 authentication
- Box for Office, Box Tools (machine-wide build), and Box Sync use a Windows Service that needs to connect to Box's data centers to check for new versions. The Windows Services run as the SYSTEM user, which may be unable to authenticate using NTLM. We recommend allowing SYSTEM run Services to connect through your proxy without authentication.
- Mac apps support NTLMv1 authentication only.
- Basic Authentication is not supported.

New Topic
A firewall is a component of network security that defines what network traffic is and is not allowed in and out of your enterprise. Firewalls can be configured as extremely as to block all inbound and outbound traffic or to allow all inbound or outbound traffic, but the former makes networking communication impossible and the latter is a significant security risk. More commonly, a firewall is either configured to allow traffic through specific ports except if explicitly blocked, or, for stricter security stances, to block traffic except if explicitly allowed.
Firewalls are configured to allow or block traffic in several ways, including by geographic source, by port, by domain/hostname, and by IP address. Box and Box applications require the traffic to and from specifically defined domains and IP addresses to be allowed through a corporate firewall, as outlined in this topic.
Typically, you would list these domains/hostnames and IP addresses in your firewall's allowlist. See the instructions for your firewall hardware or software for details.
Note
Some Enterprise accounts may need additional specific hostnames beyond what are listed in this topic. If you are using a firewall or proxy such as Forcepoint/Websense or Blue Coat, create a Box Product Support case and request additional hostnames that may be necessary for Enterprise accounts.
